Assessing Lung Function Test Behaviours in Petrochemical Workers: Safety Performance and Influencing Factors via Anderson Model

In this study, Anderson Behavioural Model is used to investigate factors influencing LFT and measure Peak Expiratory Flow Rate (PEFR) in petrochemical workers. Factors affecting participation in PFT were assessed with a questionnaire based on Anderson's Behavioural Model. A multi-stage sampling approach was employed to account for geography and workforce distribution to ensure a comprehensive representation of the petrochemical plants. This paper aims to add to the understanding of workplace health issues. Schooling level (college/university and above, OR = 0.142, P = 0.0034), and affordability of medical care, (OR = 0.348, P = 0.003) significantly influenced participation among 300 workers.Other important variables were self-care (OR = 4.92, P = 0.0005) daily activity (OR = 7.68, P = 0.0002), pain/distress (OR = 0.487, P = 0.003), concern/depression (OR = 14.40,P <0. 0001). Males showed PEFR variability at 0%, 23.3%, and 76.7% and females at 0%, 2%, and 98%. Education in improving PFT participation, financial stability, respiratory health awareness and psychological support is needed to improve PFT participation. Adverse effects of hazardous chemicals need preventative measures as they can be prevented with comprehensive respiratory health checks and educational initiatives. Surmounting financial and knowledge barriers is necessary to increase lung function test participation by petrochemical workers.
